Abstract

BACKGROUND

The art of cardiac auscultation is an essential clinical skill being lost amid growing reliance on modern technology and the steady decline in bedside teaching in the wake of the COVID-19 pandemic.

OBJECTIVES

This study aimed to assess the cardiac auscultatory skills of post-graduate trainees within a single-center design before and after a virtual simulation-based training course and to determine the effectiveness of this teaching method on improving diagnostic proficiency.

METHODS

Fifty-eight residents attended a seven-hour virtual simulation-based training course on cardiac auscultation, one hour per month, during their daily graduate medical education sessions. Residents completed a pre-test and post-test on their ability to diagnose 12 important heart sounds and murmurs produced via Harvey, the Cardiology Patient Simulator. Scores were compared using a two-tailed test. Residents also completed a feedback survey before and after the course.

RESULTS

All 58 residents completed the course as well as the pre- and post-quiz. Of the 12 auscultatory events analyzed, an overall pre-test identification score of 27.44% and a post-test score of 39.08% (an increase of 42%) were observed, with a response rate of 100%. This represents a statistically significant improvement in diagnostic proficiency (p<0.001).

CONCLUSIONS

Although not a substitute for in-person bedside teaching, a virtual simulation-based training course is an effective method of teaching cardiac auscultatory skills and improving the diagnostic proficiency of post-graduate trainees in the COVID-19 era.

摘要

背景

心脏听诊技术是一项重要的临床技能，但在对现代技术的依赖日益增加以及新冠疫情导致床边教学稳步减少的情况下，这项技能正在逐渐失传。

目的

本研究旨在通过单中心设计评估研究生学员在基于虚拟模拟的培训课程前后的心脏听诊技能，并确定这种教学方法对提高诊断能力的有效性。

方法

58名住院医师在其日常研究生医学教育课程期间，每月参加一次为期一小时、共七小时的基于虚拟模拟的心脏听诊培训课程。住院医师完成了关于诊断通过心脏病患者模拟器哈维产生的12种重要心音和杂音能力的预测试和后测试。使用双尾检验比较分数。住院医师还在课程前后完成了一份反馈调查。

结果

所有58名住院医师均完成了课程以及预测试和后测试。在分析的12项听诊事件中，观察到总体预测试识别分数为27.44%，后测试分数为39.08%（提高了42%），回复率为100%。这表明诊断能力有统计学上的显著提高（p<0.001）。

结论

虽然基于虚拟模拟的培训课程不能替代面对面的床边教学，但它是在新冠疫情时代教授心脏听诊技能和提高研究生学员诊断能力的一种有效方法。
